Описание
Memory leak in net/vmxnet3.c in QEMU allows remote attackers to cause a denial of service (memory consumption).
A memory-leak flaw was found in the QEMU emulator built with VMWARE VMXNET3 paravirtual NIC emulator support. The flaw occurred when a guest repeatedly tried to activate the VMXNET3 device. A privileged guest attacker could use this flaw to leak host memory, resulting in denial of service on the host.
